Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a communication terminal device, and more particularly, to transmitting a signal indicating a recording paper width capability indicating a recordable recording paper size during communication with a calling station. The present invention relates to a communication terminal device that receives image information of a document sent from a calling station and outputs the image information to a recording sheet set on a tray.

[0002]

2. Description of the Related Art Conventionally, in a facsimile machine, the receiving side declares the width (recording paper width capability) of recording paper such as A3, B4, A4 using an initial identification signal and the like, and the transmitting side declares the declared recording paper width capability. The transmission control method of transmitting the image information of the document of the size corresponding to the above is adopted. In particular, if the image information of the original sent from the transmitting side has a plurality of sizes and the receiving side can also set recording sheets of a plurality of sizes on the tray, a more sophisticated transmission control method is required. Become.

As such a transmission control control method, Japanese Patent Application Laid-Open No. 02-284576 proposes the following technique. That is, in a transmission control method of a facsimile apparatus that can use a plurality of types of recording paper and has an image information storage function, the receiving apparatus sets the maximum paper size that the receiving apparatus can use at its own terminal when receiving a call. Notify the maximum paper size that can be recorded at that time to the transmitter,
When the size of the transmitted image is equal to or smaller than the maximum paper size that can be used by the receiving device, the transmitting device transmits the transmission image information in the normal size mode, and the size of the transmitted image is the maximum paper size that can be used by the receiving device. When it is larger than the size, the transmission image is transmitted in a state of being reduced to the paper size, while the reception device directly transmits the reception image when the paper size notified from the transmission device is equal to or smaller than the maximum recordable paper size. In addition to recording and outputting at the same size, if the paper size notified from the transmitting device is larger than the maximum recordable paper size, the received image is temporarily stored and the maximum usable recording paper is set. The guidance is displayed on the screen, and when the maximum usable recording paper is set, the received image that has been accumulated is printed out in the same size.

However, in recent years, it has become possible to set the recording paper in both the horizontal and vertical directions on the transmitting side and the receiving side, and in which direction the recording paper is set by simply declaring the width. Cannot be distinguished on the sending side,
There is a problem that it cannot be dealt with when the orientation of the read document and the orientation of the recording paper are different. In particular, when recording a document whose length in the sub-scanning direction is longer than that in the sub-scanning direction on a recording paper set in the sub-scanning direction, simply enlarge or reduce the image information. Then
There is a problem that the received image information for one page may be divided into two pages and printed.

In order to solve this problem, Japanese Patent Publication No. 07-0
According to Japanese Patent Laid-Open No. 95802, the size of the read document is compared with the declared size of the recording paper, and if the read document orientation and the recording paper orientation are different, the image information of the document is rotated by 90 degrees. The technique of transmitting from is proposed.

[0006]

However, in the prior art described in the above Japanese Patent Publication No. 07-095802, the transmitting side has the complicated and costly function of rotating the image information of the original by 90 degrees as described above. However, in communication with a transmission device that does not have such a function, there is a problem in that the receiving side still cannot easily deal with the case where the orientation of the original is different from the orientation of the recording paper.

By the way, in recent years, from the viewpoint of energy saving, a technique has been proposed in which the power is turned off during a time of low usage frequency such as nighttime and is turned on when an incoming call comes in. Further, there is a technique in which when a call comes in, only the communication control unit is turned on, and the power of the printing device (printer) is kept off while the power of the printing device is turned on when communication is completed and printing is started. In the case of the latter technology, communication is started when a call arrives, but the recording paper set in the tray cannot be confirmed because the power of the printing device is off.In this case, the recording paper width of the initial identification signal or transmission command signal There is a problem that it is unclear which recording paper size should be set for the ability.

The present invention has been made in view of the above facts. It is possible to declare the recording paper width capability even when the recording paper size cannot be determined, and the orientation of the received original and the orientation of the recording paper can be determined. It is an object of the present invention to provide a communication terminal device that can easily cope with different cases.

[0009]

In order to solve the above-mentioned problems, the invention of claim 1 is a signal indicating a recording paper width capability indicating a size of recording paper which can be recorded during communication with a calling station. In the communication terminal device for receiving the image information of the original document sent from the calling station after outputting the message and outputting the image information to the recording paper set in the tray, a storage means for storing a predetermined recording paper width capability. And a determination unit capable of determining at least one of the recording paper size of the recording paper set in the tray and the recording paper tray size that is the size of the recording paper settable in the tray, and communication with the calling station. During execution, if the determination unit cannot determine the recording paper size, or if neither the recording paper size nor the recording paper tray size can be determined, the predetermined value stored in the storage unit is determined. And signal control means for displaying the recording paper width capability to said signal, characterized by having a.

According to the first aspect of the present invention, when the recording paper determination means cannot determine the recording paper size while the signal control means is performing communication with the calling station, or when the recording paper size and the recording paper tray size are not satisfied. If neither can be determined,
The predetermined recording paper width capability stored in the storage means is displayed on a predetermined signal. Then, the communication terminal device, after transmitting a signal indicating the predetermined recording paper width capability, receives the image information of the document sent from the calling station, and the image information of the recording paper set in the tray. Output to.

Here, as the above-mentioned signal, a signal for each initial period (in the normal ITU-T recommended T.30 procedure, NSF signal or D
An IS signal) or a transmission command signal can be used. Further, the received image information may be stored in the memory, and the stored image information may be output to the recording paper after the communication with the calling station is completed.

As described above, according to the present invention, even when the recording paper size cannot be determined, or when neither the recording paper size nor the recording paper tray size can be determined, the calling station has a predetermined recording paper width capability. Can be declared to.

According to the second aspect of the present invention, during execution of communication with the calling station, after the signal indicating the recording paper width capability indicating the size of the recording paper that can be recorded is transmitted, the signal is transmitted from the calling station. In a communication terminal device that receives image information of a document and outputs the image information to a recording sheet set in a tray,
A recording paper determination unit that can determine the recording paper size of the recording paper set in the tray, a tray size determination unit that can determine the recording paper tray size that is the size of the recording paper that can be set in the tray, During the communication with the call station, if the recording paper determination means cannot determine the recording paper size, the recording paper width capability is determined based on the recording paper tray size determined by the tray size determination means, and is determined. And a signal control means for displaying the recording paper width capability in the signal.

According to the second aspect of the present invention, when the recording paper determination means cannot determine the recording paper size while the signal control means is performing communication with the calling station, the recording paper determined by the tray size determination means. The recording paper width capability is determined based on the tray size, and the determined recording paper width capability is displayed on the signal. In this case, the maximum size of the recording paper tray sizes determined by the tray size determination means may be displayed as the recording paper width capability.

As described above, according to the present invention, even when the recording paper size cannot be determined, the recording paper width capability determined based on the recording paper tray size can be declared to the calling station. Note that the recording paper size cannot be determined in some cases, such as when there is no more recording paper set in the tray, and even in such a case, the calling station sends image information processed based on the recording paper tray size. Will be sent, so if the recording paper is set in the tray, it can be recorded immediately.

[0016]

[0017]

[0018]

According to the third aspect of the present invention, during the communication with the calling station, a signal indicating the recording paper width capability indicating the size of the recording paper that can be recorded is transmitted, and then the original document transmitted from the calling station is transmitted. In a communication terminal device that receives image information and outputs the image information to a recording sheet set in a tray, the length in the main scanning direction and the length in the sub scanning direction of the recording sheet set in the tray are determined. When even one kind of recording paper having a length in the sub-scanning direction longer than the length in the main scanning direction is set in the tray during communication between the deciding length determining means and the calling station, The recording paper width capability is determined based on the size of the recording paper which is longer in the sub-scanning direction, and when only the recording paper whose length in the main scanning direction is longer than the length in the sub-scanning direction is set in the tray, it is set. Length of recording paper in main scanning direction And a signal control unit for displaying the determined recording paper width capability on the signal.

In the invention of claim 3 , the signal control means is
During communication with the calling station, if even one type of recording paper whose length in the sub-scanning direction is longer than that in the main-scanning direction is set in the tray, the recording paper that is longer in the sub-scanning direction is The recording paper width capability is determined based on the size. In this case, the maximum size of the recording paper sizes that are longer in the sub-scanning direction may be determined as the recording paper width capability.

On the other hand, when only the recording paper whose length in the main scanning direction is longer than that in the sub scanning direction is set in the tray, the recording paper width capability is based on the length of the set recording paper in the main scanning direction. To decide. In this case, the maximum length of the set recording papers in the main scanning direction may be determined as the recording paper width capability.

Since there are generally more types of recording paper of one kind set in the tray, the length of which in the sub-scanning direction is longer than that of the main-scanning direction. It is considered that the recording paper width capability is often determined based on the size of the recording paper having a long length.

When a document whose length in the sub-scanning direction is longer than that in the sub-scanning direction is recorded on a recording sheet set so that the length in the main-scanning direction is longer than that in the sub-scanning direction, the image information is simply enlarged or reduced. Just by doing, the received page image information is
Although it may be divided into pages for recording, in the present invention, since it is possible to perform recording on a recording paper whose length in the sub scanning direction is longer than that in the main scanning direction as described above, It is possible to suppress the occurrence of various divided recordings. Therefore, there is an advantage that the recorded image information is easy to see.

Further, the facsimile apparatus 10 has a function of discriminating the size (recording sheet size) of the recording sheet set in each tray of the printing apparatus 20. This function can be achieved, for example, by allowing the printing device 20 to read the position of the cut-off plate used for positioning the recording paper in the tray when the tray can set recording papers of a plurality of sizes. Further, in the case where only one kind of size can be set in the tray, it can be realized by providing an information code indicating a settable recording paper size to the tray and making the information code readable by the printer 20. The information read by the printing device 20 is transmitted to the CPU 12.

Further, the facsimile apparatus 10 has a function of discriminating the size of recording paper (recording paper tray size) that can be set in each tray. For this function, for example, one or a plurality of information codes respectively indicating all settable recording paper sizes (may be a plurality of sizes) are provided to each tray so that the printer 20 can read the information codes.

The storage device 42 stores the recording paper width capability that is declared when the recording paper size cannot be determined. As the recording paper width capability, the maximum width A3 size may be stored or the minimum width A4 size may be stored.

The facsimile apparatus 10 of the present embodiment is
Although it is possible to connect to both a digital network and an analog network, when the facsimile device 10 is connected only to an analog network, the digital communication control program storage unit 30 and the digital network control device 38 can be omitted, and the digital network can be connected. In the case of connecting only to, the analog communication control program storage unit 32, the modem 34 and the analog network control device 40 can be omitted.

Next, the operation of this embodiment will be described with reference to the flowchart of FIG. Note that the flowchart of FIG. 2 shows the flow of processing when the facsimile apparatus according to the present embodiment is the transmission side that receives image information of a document, and as shown in FIG. T Recommendation T. 30 protocol procedures are taken as an example. Where I
TU-T stands for International Telecommunications Uni
On-Telecommunications Standardization Sector, meaning the Telecommunications Standardization Sector of the International Telecommunications Union.

As shown in the flow chart of FIG. 2, first, the CPU 12 reads out the recording paper width capability for declaring when the recording paper size cannot be discriminated when the power is turned on from the storage means 42, and the recording paper width capability ( For example, A3 size is stored in the RAM 14 (step 10).
0).

Then, it is determined whether or not there is an incoming call from the calling station (step 102), and if there is no incoming call (step 102 negative determination), the system waits in that state.

When there is an incoming call from the calling station (Yes at Step 102), CED (Ca
lled Station Identification) signal is transmitted (step 104). As a result, the called terminal is confirmed at the calling station, and the line establishing sequence is completed (see FIG. 4).

Next, it is determined whether or not the size of the recording paper (recording paper size) set in the tray of the printer 20 can be determined (step 106). As a case where all the recording paper sizes cannot be discriminated, there is a case where the recording papers are exhausted in all the trays.

If all the recording paper sizes cannot be discriminated (No at Step 106), then it is judged whether the recording paper sizes that can be set in the tray (recording paper tray size) can be discriminated. (Step 108). In addition, as a case where all the recording paper sizes cannot be discriminated, there is a case where the power of the printing device 20 is turned off for energy saving.

When all the recording paper tray sizes cannot be discriminated (No at step 108), that is, when neither the recording paper size nor the recording paper tray size can be discriminated, the recording read to the RAM 14 at step 100. The paper width capability is determined as the recording paper width capability to be actually set (step 110).

On the other hand, when the recording paper size cannot be discriminated but the recording paper tray size can be discriminated (step 108).
(Affirmative determination), all the discriminating recording paper tray sizes are read out to the RAM 14 (step 111). Then, the maximum recording paper tray size of the read recording paper tray sizes is determined as the recording paper width capability (step 11).
2).

If even one recording paper size can be discriminated (Yes at Step 106), all the discriminating recording paper sizes are read out to the RAM 14 (Step 11).
4). Then, the maximum recording paper size among the read recording paper sizes is set as the recording paper width capability (step 11).
9).

As described above, steps 110, 112, 1
When the recording paper width capability is determined in any one of 19, the recording paper width capability is set to the NSF which is the initial identification signal.
(Non-Standard Facilities) signal or DIS (Digi
TAL Identification Signal) signal is set in the facsimile information field (FIF) and sent to the calling station (step 120).

The NSF signal is a signal for identifying the calling station that it has a non-standard function that is outside the range of the T series recommendation, and the DIS signal is a signal that the called terminal has a standard reception function. This is a signal for indicating the fact to the calling station. When the calling station receives this signal, it analyzes the facsimile information field of the signal to detect the recording paper width capability of the answering station.

Then, even after this, the usual ITU-T recommendation T.264. Communication is performed according to the communication procedure of 30 (step 122).
That is, as shown in FIG. 4, NSF signal or DIS
The calling station that receives the signal instructs the function to be set from the functions displayed by the answering station to the NSS (Non-
Standard facilities Set-up) signal is sent. next,
After the line training is executed, the preparation for image information transfer is completed. After that, the process moves to the image information reception phase, and the image information is transferred from the calling station to the response station. When the image information receiving phase ends and the communication ends due to the disconnection of the line, the process returns to step 102 and waits again for an incoming call from the calling station.

As described above, in the first embodiment, even if neither the recording paper size nor the tray size can be discriminated, the recording paper width capability stored in advance is set in the initial identification signal (steps 110, 120). Therefore, it is possible to avoid the situation where the recording paper width cannot be declared. For this reason,
It is desirable to use the size of the recording paper that is most likely to be set, as the recording paper width capability stored in advance.

Even if all the trays are full of recording paper and the recording paper size cannot be discriminated, if the recording paper tray size can be discriminated, the maximum recording paper tray size is set as the recording paper width capability in the initial identification signal. (Step 112), it is possible to effectively declare the recording paper width. Even if the recording paper is not set in this way, it is possible to cope with the problem by displaying the guidance to set the recording paper after receiving the image information.

Further, if even one recording paper size can be discriminated, only the size in which the recording paper is set is declared as the recording paper width capability (step 119), so that the recording paper is set as in the conventional case. The trouble of displaying the guidance and recording and outputting the stored received image when the recording paper is set is omitted, and the received image information can be immediately printed and discharged. (Second Embodiment) Next, a second embodiment will be described. Since the configuration of the second embodiment is similar to that of the first embodiment, the same reference numerals are given and detailed description thereof is omitted.

However, the CPU 12 sets the length of the recording paper set in each tray of the printing device 20 in the main scanning direction (printing direction of one line) and the sub-scanning direction (perpendicular to the main scanning direction in the recording surface). Direction or the length of the recording paper ejection direction). This function is enabled by making the printer 20 readable at the position in the main scanning direction and the position in the sub scanning direction of the dividing plate used for positioning the recording paper in the tray.

The operation of the second embodiment will be described with reference to the flowchart of FIG. It should be noted that the same operation parts as those in the flowchart of FIG. 2 are denoted by the same step numbers, detailed description thereof will be omitted, and only different operation parts will be described.

As shown in the flowchart of FIG. 3, when the recording paper size can be discriminated (Yes at Step 106), all the discriminating recording paper sizes are read (Step 114). At this time, the length in the main scanning direction (hereinafter, referred to as “main scanning length”) and the length in the sub scanning direction (hereinafter, referred to as “sub scanning length”) of all the identifiable recording papers are detected. .

Next, it is determined whether the main scanning length of all the identifiable recording papers is larger than the sub scanning length (step 115). If even one type of recording paper whose sub-scan length is longer than the main-scan length is set in the tray (No determination in step 115), the largest recording paper size is recorded among the recording papers whose sub-scan length is longer. It is determined as the paper width capability (step 116). The calling station that has declared the recording paper width capability enlarges or reduces the image information of the document to fit this width as much as possible, and then sends it.

On the other hand, if the main scanning length is longer than the sub-scanning length for all the identifiable recording papers (Yes at Step 115), the main scanning length of the recording paper size with the longest main scanning length is set. It is determined as the recording paper width capability (step 118).

The processing after the recording paper width capability is determined in steps 116 and 118 as described above is the same as in the flow chart of FIG.

As described above, in the second embodiment, since it is possible to print on the recording paper whose sub-scan length is longer than the main-scan length as much as possible, the received image information for one page is divided into two pages. There is an advantage that the number of divided prints is extremely reduced and the printed image information is easy to see.

Although the embodiments of the present invention have been described above, the present invention is not limited to the above examples. For example,
In each of the above embodiments, the normal ITU-
Recommendation T. 30 is taken as an example, but other G3 protocol procedures such as ITU-T Recommendation T.30. A 30 ANNEX F procedure can also be used. It is also applicable to procedures other than the G3 protocol procedure, such as the G4 protocol procedure. Of course, the type of the initial identification signal having the information on the recording paper width capability can be arbitrarily changed according to each protocol procedure.

Further, in each of the above embodiments, the recording paper width capability is declared by using the initial period signal (NSF signal or DIS signal), but the recording paper width capability is declared by a signal other than this, for example, a transmission command signal. You may.

Further, in the flowcharts of FIGS. 2 and 3, when the recording paper size cannot be discriminated (step 1
06 negative determination), immediately in step 100 RAM14
The recording paper width capability stored in the table may be determined as the recording paper width capability to be declared (step 110). This process is effective when the recording paper tray size is not provided.

Although it is assumed that there are a plurality of trays, the present invention can be applied to one tray.

[0057]

As described above, according to the first and second aspects of the present invention, it is possible to declare the recording paper width capability even when the recording paper size cannot be determined.

[0058]

Further, according to the invention of claim 3 , the received image information is recorded on a recording paper whose length in the sub-scanning direction is as long as possible in the main scanning direction by a very simple method. Since it is possible to record the image information for one page divided into two pages, the recorded image information can be easily viewed.
